HBASE-3094 Fixes for miscellaneous broken tests

M src/test/java/org/apache/hadoop/hbase/HBaseTestingUtility.java
  Added passing a Configuration to createTable.
M src/test/java/org/apache/hadoop/hbase/HBaseClusterTestCase.java
  Make a new configuration each time we create a cluster else this
  old testing utility fails when we do restart in middle of a test
  suite using this old stuff.
M src/test/java/org/apache/hadoop/hbase/regionserver/TestHRegion.java
  Fixed imports.
M src/test/java/org/apache/hadoop/hbase/MiniHBaseCluster.java
  Added catch for other than IOE... shutdown if anything thrown.
M src/test/java/org/apache/hadoop/hbase/master/TestCatalogJanitor.java
  This test was for sure horked.  Fixed it so we were testing
  the javadoc description of how its supposed to work.
M src/test/java/org/apache/hadoop/hbase/master/TestDeadServer.java
  Another test that just wasn't working -- couldn't have worked on
  commit.
M src/test/java/org/apache/hadoop/hbase/master/TestLoadBalancer.java
  Must have resolvable host (How did this test ever work)?
M src/test/java/org/apache/hadoop/hbase/client/TestGetRowVersions.java
   Fixup to make this test pass.  New Configuration after cluster restart.
M src/test/java/org/apache/hadoop/hbase/client/TestScannerTimeout.java
  Fixup to make this test pass.  The low scanner timeout was stopping
  this test from even starting up.
M src/test/java/org/apache/hadoop/hbase/client/TestFromClientSide.java
  Use new method from HTU.
M src/main/java/org/apache/hadoop/hbase/regionserver/SplitTransaction.java
  If passed server is null, we are in test mode.
M src/main/java/org/apache/hadoop/hbase/catalog/CatalogTracker.java
  Catch other dropped connection exception types when trying to prove
  we have a good root/meta address.
